So my lil girl and I went to the railroad museum ,she couldnt resist into going into one of the old cars. So I thought I would play around with a new process in PP. I know that there is pole coming out of her head.

My comments or suggestions below are not a criticism of you, your model, your talent or skill. I offer them in a friendly tone of voice and with the sole intent to help you with a second POV and set of eyes. If you read sincere questions and simple suggestions as "criticism" of you, then you will miss how I am trying to help you.

Of course this may be your own "style" or your own "vision" and I suppose we can assume that the images look just like they do because that is exactly how you like them. That is OK too. It just shows that there are differences of "opinion" on what looks good. IF these are exactly what you want and like, then by all means continue making your images look like that and have fun doing it. I can only speak for myself and what I do or do not find appealing in the posted photos. As I always say: "Follow your own muse."

I would prefer to see the child doing something (active), such as exploring the place or walking or just about anything rather than sitting as shown. Her static position and expression give me this impression:

Like. I think she is showing a legitimate childhood emotion. Kids don't always smile or look enjoyed. I like wondering "What is she thinking?" It becomes more than a "family portrait" especially considering the environment.
